3 FUNCTION
4 <<wmempcpy>>---copy wide characters in memory and return end pointer
5
6 SYNOPSIS
7 #define _GNU_SOURCE
8 #include <wchar.h>
9 wchar_t *wmempcpy(wchar_t *<[d]>,
10 const wchar_t *<[s]>, size_t <[n]>);
11
12 DESCRIPTION
13 The <<wmemcpy>> function copies <[n]> wide characters from the object
14 pointed to by <[s]> to the object pointed to be <[d]>. This function
15 is not affected by locale and all wchar_t values are treated
16 identically. The null wide character and wchar_t values not
17 corresponding to valid characters are not treated specially.
18
19 If <[n]> is zero, <[d]> and <[s]> must be a valid pointers, and the
20 function copies zero wide characters.
21
22 RETURNS
23 <<wmempcpy>> returns a pointer to the wide character following the
24 last wide character copied to the <[out]> region.
25
26 PORTABILITY
27 <<wmempcpy>> is a GNU extension.
28
29 No supporting OS subroutines are required.
